The sublime and the beautiful.
The concept of classical music conjures up images of symmetry,
refinement and even delicacy but the music itself can in fact
express much emotion, from the often violent expressiveness of
Bach to the sublime melodies of Mozart. Dittersdorf,
Mozart’s friend, once wrote: “He was so astonishingly rich in
ideas I could only wish he had not been so extravagant with
them. He gives the listener no time to draw breath; for when one
wants to ponder one beautiful idea there is another even finer
one to drive the first away, and so it goes on …” Such
creativity both astonished and baffled many of Mozart’s
contemporaries.

So did the logic with which he developed his ideas. Each feeds
on and emerges from its predecessor with such inevitability that
the music reflects unity as a skilfully cut diamond reflects
light; each facet has its own fascination but is part of the
majesty of the whole. Mozart gives an important clue to his
intentions in a letter to his father when he says of some of his
piano concertos that they are a “happy medium between what is
too easy and too difficult; they are brilliant, pleasing to the
ear, and natural without being too vapid. There are passages
here and there from which connoisseurs can derive satisfaction;
but these passages are written in such a way that the less
learned cannot fail to be pleased, though without knowing why.”

Piano Concerto No. 7 for two or three pianos, "Lodron"
in F major K.242. Mozart
originally wrote it in February 1776 for three pianos. However,
when Mozart himself eventually played this concerto in 1780, in
one of his last public performances in Salzburg, he rearranged
it for two pianos, a version that makes greater demands on the
soloists. In his classic biography of the composer - about
Mozart's keyboard concertos - Alfred Einstein writes
"…we shall not concern ourselves further with the purely galant Concerto for
Three Pianos…” Mozart wrote it for his noble patrons,
Countess Maria Antonia Lodron, and her two daughters and cast
his patroness and her daughters in the most flattering light in
the concerto. But, of course, Mozart could never be expected to
conform to the demands of genteel society, and the concerto ends
with a little joke - a trick coda, followed by the real thing.

Piano Concerto No. 23 in A major K.488.
In 1784, Mozart began his Catalogue of all my Works.
Between January 1784 and December 1786 Mozart composed 12 piano
concerti, all of them masterpieces.Among them,
Piano Concerto No. 23 was composed for subscription concerts, or
academies, that Mozart held during the winter months to
earn a living. Mozart’s musical mind, as we know it, is
abundantly evident in the first movement of Piano Concerto No.
23 and proceeds in an elegant and stately fashion to the second
movement with its beautiful, gentle and lyrical melody in an
atmosphere of peacefulness and tranquillity. The third movement
carries over the melody and brings us back to the majesty of the
first movement and on to a joyous finale.
